Antidepressant drugs such as Prozac were viewed in the early 1900's as wonder pills that would remove depressive blues for good. But in the past five years, growing scientific evidence has shown these drugs work for only a minority of people. And now a research journal says that these antidepressants can make many patients' depression worse. This alarming suggestion centres on the very chemical that is targeted by antidepressants-serotonin . Drugs such as Prozac are known as selective serotonin re-uptake inhibitors(or SSRIs). Their aim is to increase the level of this  "feel-good" chemical in the brain. But the new research, published in the journal Frontiers In Evolutionary Psychology, points out that serotonin is like a chemical Swiss Army knife, performing a very wide range of jobs in the brain and body. And when we start changing serotonin levels purposely, it may cause a wide range of unwanted effects. These can include digestive problems and even early deaths in older people, according to the study's lead researcher Paul Andrews. " We need to be much more cautious about use of these drugs," says Andrews, an assistant professor of evolutionary psychology at McMaster University in Ontario, Canada. Previous research has suggested that the drugs provide little benefit for most people with mild depression, and actively help only a few of the most severely depressed. Famous psychologist Irving Kirsch has found that for many patients, SSRIs are no more effective than a placebo pill. A research in 2010 on Danish children found a small, but significant, increase in the risk of heart problems among babies whose mothers had used SSRIs in early pregnancy. The key to understanding these side-effects is serotonin, says Andrews. Serotonin is also the reason why patients can often end up feeling still more depressed after they have finished a course of SSRI drugs. He argues that SSRI antidepressants disturb the brain, leaving the patient an even greater depression than before. "After long use, when a patient stops... In Stafford Lightman's opinion,  _  . A) drug companies don't know the negative effect of antidepressants B) Andrews focused on different things from the drug companies C) scientists have found what SSRIs do in the brain D) Andrews' research has no medical value

Why do Americans struggle with watching their weight, while the French, who consume rich food, continue to stay thin? Now a research by Cornell University suggests how life style and decisions about eating may affect weight. Researchers conclude that the French tend   to stop eating when they feel full. However, Americans tend to stop when their plate is empty or their favorite TV show is over. According to Dr. Joseph Mercola, a health expert, the French see eating as an important part of their life style. They enjoy food and therefore spend a fairly long time at the table, while Americans see eating as something to be squeezed   between the other daily activities. Mercola believes Americans lose the ability to sense when they are actually full. So they keep eating long after the French would have stopped. In addition, he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week. The French, instead, tend to shop daily, walking to small shops and farmers' markets where they have a choice of fresh fruits, vegetables, and eggs as well as high-quality meats for each meal. After a visit to the United States, Mireille Guiliano, author of French Women Don't Get Fat, decided to write about the importance of knowing when to stop rather than suggesting how to avoid food. Today she continues to stay slim and rarely goes to the gym. In spite of all these differences, evidence shows that recent life style changes may be affecting French eating habits. Today the rate of obesity - or extreme overweight - among adults is only 6%. However, as American fast food gains acceptance and the young reject   older traditions, the obesity rate among French children has reached 17% - and is growing. In what way are the French different from Americans according to Dr. Joseph Mercola? A) They go shopping at supermarkets more frequently. B) They regard eating as a key part of their life style. C) They squeeze eating between the other daily activities. D) They usually eat too much canned and frozen food.

For a stay-at-home mom, a computer with an Internet connection can truly be a lifeline . When diapers and baby talk become just too much, adult talk is just a click away. But for some moms, the attraction of the online world becomes too strong to resist  and instead of being an occasional thing, it becomes an addiction . Coleen Moore of the Illinois Institute for Addiction Recovery says she is seeing a growing number of young stay-at -home moms for whom blogs and social networking have become a passion, which will harm their real-world lives. Now, Internet addiction is not officially recognized as a mental disorder. But a recent survey showed 14 percent of Internet users find it hard to stay away from their computers for several days at a time, and that 8 percent use the Web to escape problems. Considering this, it is probably just a matter of time before it is. What drives a mom to the Internet is not different from what drives an alcoholic  to drink: an empty place that needs filling. "In addiction treatment, we talk about the fact that there's a void ,"says Moore. "Whatever that void may be -- whether it's emotional, spiritual, physical--we're trying to fill it." So, how can you find the void? A journal tracking when and why you go online and what you may be avoiding when you do so can be helpful in finding it out. But what makes Internet dependence special is the fact that usually it is not just a way to escape the tiring parenting or make a connection with others, but also a way to make a statement and be heard. If a mom wants to get rid of Internet addiction, she should   _  . A) talk to online friends B) try to fill the empty space in life C) create a new online name D) ask an alcoholic for some advice
